We smell a new squad in our midst!
However, it appears the epic collaborative performance gave an even cooler gift in the form of new best friends, Blue Ivy Carter and Apple Martin.
For the snap, the Oscar winner wrote:
Steven Tyler is going to have a new son soon!
No, it isn't because he knocked anyone up! It's because his daughter Chelsea Tyler is set to marry a fellow by the name of Jon Foster!
Steven isn't just inheriting any old son-in-law though, because Jon happens to be the brother of super under-utilized actor Ben Foster! Seriously — someone get Ben and Joseph Gordon-Levitt in a movie together already!!
The happy engagement news was first broken by Chelsea's older half-sister Mia Tyler!
"I'm beyond excited and proud to say that these two turkeys are gettin hitched. I love you two to the god damn moon!"
The soon-to-be honeymooners aren't just any regular love partners. They're also music partners!
The two play in a band called BadBad, which is an electronic soul group!
Hey - maybe as a wedding present - Steven will let them play alongside Aerosmith! They might not mesh stylistically, but how cool would that be for them???
Congratulations you two!
Check out a funny picture of the music-lovers duo (below) !!!
